Epileptic Seizures in SecondLife

By Avatar JayR Cela

This is an old issue, and quite frankly I do not know if LL has any control over it. We all know that Particle Effect's in a Virtual World environment ca be quite spectacular and memorizing. However there is unintended potential for harm.

People that are afflicted with the RL condition know as Epilepsy may inadvertently find themselves in a situation that could result in, at worst case an Epileptic Seizure. There is an International Standard known as the "W3C guidelines on Red Flash" ( You will have to do some research on you own for this one )

The fact, at least in my mind is. LL has completely dropped the ball on people in SL with disabilities and Viewer 2. The issue is an old one, and it deeply disturb's me. V2 is cumbersome, difficult to use, requires way to many mouse click's to accomplish tasks that use to be simple. I don't know what planet these folk's are living on, but it's not mine.

Later this week I will have a post from a professional in the field of Epileptic Treatment Therapy, to share her view's and what can possibly be done to circumvent this potential for unnecessary harm to afflicted SL residents.

The zero-particles method you describe always worked with Viewer 2 as well

By the way "CTRL ALT SHIFT =" is a completely acceptable shortcut. Creating new shortcuts isn't trivial - you would be surprised of the complexity that shortcuts imply, given all keyboards/layouts differences across the world.
